Message stating The User Profile Service service failed the sign-in. User profile can't be loaded when attempting to login

I have a Lenovo Ideapad Flex-4 (bought this January 2017, so fairly new device) & i have noticed that my laptop has been getting slower & slower in the past couple of days. It freezes up randomly & some programs that i use are "not responding" more frequently. Last night once I was done using my laptop I turned off my laptop & I forgot I had to send my mom a PDF file so I turned it back on & I had a black screen (w/a white movable curser only) for roughly 30 mins I thought my computer Was screwed at this point. Shortly after the 30 min wait, it finally opened up the screensaver to let me login to my user profile. I then input my password (which inputting each letter was awfully slow also). After it was loading for a good 10 mins, this message popped up "The User Profile Service service failed the sign-in. User profile can't be loaded" I'm ffreaking out! My mom just bought me this laptop as a gift & I hope its not screwed up for good because i'm literally in tears right now. Oh & also, I don't know if this may have anything to do with it (personally I don't think so because my laptop was already getting slower from start up as of yesterday but never not letting me login) but i did set a magnet on top of my laptop near the lower right corner (right of the touchpad & bottom right of keyboard) it wasn't a big magnet at all, I've just heared stories about magnets possibly messing up a laptop but i don't know if thats true. Anyways someone Please help me out! As soon as possible Please & Thank you!
